9 Claims.

This invention relates in general to a lighting xture having a movable lamp support and has more particular reference to a wall type of X- ture in which a mirror or another reflecting element forms a support and background for the lamp or lamps.

One of the objects of the invention is in the provision of a wall type of fixture having a reflector plate in which the lighting elements are directly mounted and are movable to vary the position thereof.

A further object of the invention is in the provision of an improved roller mounting for a lamp support.

A further object ofA the invention is in the provision of a resilient slot closing plate engaged at the rear by the fixture mounting.

A still further object of the invention is in the provision of shields in connection with the lamps for a wall fixture of this kind which are movable to cover or uncover the lamps.

A still further object of the invention is in the provision of a simple fixture support which is easily movable without binding in a narrow slot and is supported by spaced rollers at the rear which permit movement with the least friction requiring no resilient engaging means as a part of the lamp mounting itself.

Other objects will appear hereinafter, the preferred construction being illustrated in the accompanying drawing.

The present invention provides a sliding lamp holder which is attached to or mounted directly in a reflecting plate such as a mirror so that the mirror is in fact the lamp support. In mounting the movable lamp supports along or close to the edge of a mirror of glass or other easily broken material, it is desirable that the lamp support be movable with as little friction or bending of the parts as possible and the present mounting is particularly designed and intended to provide contact points at spaced distances so that no matter at what point the lamp support is engaged it may be moved in either direction in its mounting slot without flexing or bending the mirror in which it is supported. It is fur- (Cl. Z110-4.1)

holding the lamp in any adjusted position along the slide and to close or substantially close the slot at the back of the support.

In a lighting fixture of this kind it is frequently desirable to vary the lighting effect, either increasing or reducing the brilliancy of the lights or their reflection from the mirror support, and for this purpose the individual lamps are provided with shields, one or both of which may be hinged so that it may be swung into or out of the path of the light rays.

Referring now more particularly to the drawing, a supporting plate 8 is mounted in any suitable manner for attaching it to a wall or other support and may be hung by means of a suitable wire or cord 9. This plate is preferably a glass mirror and may be provided with a holder comprising marginal guides 10 in which it is removably inserted. A slot 11 is cut in the mirror glass at any desired location but preferably the slots are provided closely adjacent the vertical side edges of the mirror, leaving a narrow strip 12 of mirrored surface between the slot and the edge of the plate.

1n each slot 11 is mounted a guideway 13 which has an inner rectangular slot 14 in which a lamp holder 15 is slidably movable. The guideway preferably has a narrow flange 16 which overlaps the slot 11 so that it is inserted through the slot in the mirror from the front thereof, the iiange engaging the faces of the slot and the guideway being held in place in the slot 11 by a cross plate 17 overlapping the slot 11 at the top and bottom with a screw 18 inserted therethrough into the guideway from the rear side of the mirror.

The lamp holder 15 may be made of `material of any suitable design but is preferably hollow and carries an electric lamp holder 19 at its youter end with a lamp 20 therein and having a switch 21 for controlling the lamp. At the underside of the holder is a small decorative knob or projection which affords an easily engaged extension for raising or lowering the lamp although the fixture is designed for easily sliding movement wherever it may be engaged.

At its inner end the lamp holder 15 has openings 23 through which conductor wires 25 for supplying current to the lamp may extend, and connecting cross pieces 26 to which a roller carrying frame 27 is attached by small screws 28.k This frame 27 has a central roller 29 for engaging a slot cover plate 30 at the rear of the slot 14, and longer end rollers 31 of slightly'less diameter than the middle roller 29 for engaging inwardly projecting edges 32 of the guideway 14. Thus it is seen that the lamp holder 15 has a three point contact with the guideway 14 and with the plate 30 which holds it against rocking movement in the guideway 14 and because of the'wide loo separation of the end rollers 31, prevents a rocking action of the holder when it is engaged for movement at any portion of the holder 15.

To maintain the lamp holder 15 yieldingly in any desired position, the cover plate 30 is resiliently mounted at each end by means of an oirset bracket 33 which spaces the plate from the inner face of the guideway 14 to provide a slot 34 through which the conductor wire 25 will pass. This bracket 33 is attached to the ends of the guideway 14 by means of a screw 35 surrounding which is a spring 36 between the bracket and the head of the screw so that the spring tends to press the plate 30 tightly against the roller 29 of the lamp holder 15, the plate 30 rocking slightly about its end mountings as the lamp holder is moved in the guideway 14 and thus holding it yieldingly in any position in which it isset.

Each lamp holder may be provided with a fixed guard or shield and a hinged or movable shield 33. The movable one is hinged to a plate 39 secured to the holder 19 and has a spring clip 40 for engaging a projection 41 carried by the plate so that when the shield 39 is in raised position, the spring clip will engage the projection and hold the shield yieldingly in place, If it is desired to increase the direct illumination the outer shield 38 is turned downwardly and to increase the reilected illumination, the shield 33 is-turned upwardly. The shape of these guards or shields may be altered or varied for increased decorative effect.

With this construction it is obvious that the lamp holder may be easily operated in either direction in the slot and that it will move with a minimum resistance without rocking or binding in either direction. A slot is always provided for the electrical conductors 25 which may be looped at the rear of the mirror and connected by means of a plug or -otherwise to any suitable source of current supply. The mirror is the supporting part of the fixture and constitutes a reflector for the lamps at both sides thereof, or wherever they may be located. By positioning the slots at the vertical edges the main or interior surface of the mirror is unobstructed and by providing the narrow mirror strip 12 at the outside of the mirror slot 11, substantially the full width of the mirror is utilized, making the xture look wider and more pleasing in appearance.

It is obvious that the rear support or reflector maybe a metal plate or a glass mirror and that if' this support has suflicient rigidity, a separate guideway mounted in the support maybe omitted, the rollers 31 at the rear of the lamp support engaging directly with the rear face oi the plate at the sides of the slot.
